I thought it was supposed to give you a litte more pick-up off the line.

Maybe back in the day on engines with carburetors or throttle-body injection; since it increased the plenum volume and promoted better mixing of the fuel and air. Since direct-injection engines don't add fuel at the throttle body, the spacer won't have the above mentioned effect.

Now there is a VERY contentious (at least it was when I stopped reading it) thread in the V8 section regarding Vararam's Power Wedge TB spacer that apparently promises some modest gains (8 -12 HP) by adjusting the angle of the throttle body w/r to the flow and some TB repositioning as well. Vararam states that in increases flow. Not really sure the gains are always seen by everyone though, given individual set-ups, etc. Whether they're working on anything for the LLT/LFX, or if the concept would even work on the LLT/LFX is unknown to me.

This is true on the Vararam.....but I talked to Tracy about it and he said once the ECU relearned the spacer it provided no gains
